In the robotics community, specifically for "bristle bots" or small quadrupeds, this servo is a staple.
Physical dimensions are compact: (1.26 x 0.45 x 0.94 in), with a weight of 12 grams . This “sub-micro” form factor adheres to the standard 3x screw hole pattern, allowing drop-in replacement for many 9g-class servos despite its heavier metal construction.
